Data Processing

Generating new geospatial data by field surveys is time consuming and expensive task but it is necessary for capturing the current status of the factors under investigation. However, the wealth of existing maps, data and information is invaluable for understanding the temporal changes in those factors. C_GIS offers various services for utilising the exiting spatial and non-spatial data under strict precision and quality control measures.
